And everyone WANTS a death ray, but no one has made a practical one yet.

There are plenty of commercial death rays in the 54-72 MC and 76-88 MC
bands. They don't cause death directly, but transmissions on these
frequencies can cause severe brain damage even at low levels when demodulated
and viewed. A number of studies have shown long-term exposure to cause
all sorts of problems in children.
